Abstract: The present invention is an apparatus for holding and dispensing toilet tissue and a method of use. The toilet tissue holding and dispensing apparatus has at least an active roll position and a standby roll position, where the active roll position is at an upward angle from the standby roll position. A roll of toilet tissue is capable of being held in the active roll position by one or more pins with an angled face oriented towards the standby roll position so that the sides of a toilet tissue roll pulled from the standby roll position to the active roll position can displace the pins axially. Once a toilet tissue roll is held in the active roll position, it can rotate freely relative to the pins and the orientation of the angled faces prevents the pins from being displaced axial by a toilet tissue roll dispensing toilet tissue.

Abstract: Methods and systems for detecting early stage dental caries and decays are provided. In particular, in an embodiment, laser-induced autofluorescence (AF) from multiple excitation wavelengths is obtained and analyzed. Endogenous fluorophores residing in the enamel naturally fluoresce when illuminated by wavelengths ranging from ultraviolet into the visible spectrum. The relative intensities of the AF emission changes between different excitation wavelengths when the enamel changes from healthy to demineralized. By taking a ratio of AF emission spectra integrals between different excitation wavelengths, a standard is created wherein changes in AF ratios within a tooth are quantified and serve as indicators of early stage enamel demineralization. The techniques described herein may be used in conjunction with a scanning fiber endoscope (SFE) to provide a reliable, safe and low-cost means for identifying dental caries or decays.
